Just like flipping a switch -- in only half a picosecond

(University of Missouri-Columbia) Now, researchers at the University of Missouri have discovered spin flips happen in one half of one trillionth of a second, or half a picosecond in the course of a chemical reaction. To understand how fast it is -- watches count in seconds, sporting games are timed in 10ths of a second, and light travels just under 12 inches in one-billionth of a second. Spin flips are faster.
